Final answer:
The efferent arteriole is the blood vessel that carries blood out of the glomerulus in the kidney.
Step-by-step explanation:
The efferent arteriole is the small blood vessel that carries blood out of the glomerulus in the kidney. It is part of the renal circulation system, which filters waste products from the blood and helps regulate water and electrolyte balance. When blood enters the nephron through the afferent arteriole, it passes through the capillaries of the glomerulus. Any blood that doesn't pass through the glomerulus, as well as blood after it passes through the glomerular capillaries, continues on through the efferent arteriole.
